Balanced equation

Balance the chemical equation algebraically: KOH + NO_2 + KClO ⟶ H_2O + KCl + KNO_3 Add stoichiometric coefficients, c_i, to the reactants and products: c_1 KOH + c_2 NO_2 + c_3 KClO ⟶ c_4 H_2O + c_5 KCl + c_6 KNO_3 Set the number of atoms in the reactants equal to the number of atoms in the products for H, K, O, N and Cl: H: | c_1 = 2 c_4 K: | c_1 + c_3 = c_5 + c_6 O: | c_1 + 2 c_2 + c_3 = c_4 + 3 c_6 N: | c_2 = c_6 Cl: | c_3 = c_5 Since the coefficients are relative quantities and underdetermined, choose a coefficient to set arbitrarily. To keep the coefficients small, the arbitrary value is ordinarily one. For instance, set c_3 = 1 and solve the system of equations for the remaining coefficients: c_1 = 2 c_2 = 2 c_3 = 1 c_4 = 1 c_5 = 1 c_6 = 2 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: |   | 2 KOH + 2 NO_2 + KClO ⟶ H_2O + KCl + 2 KNO_3
